摘要

为了解决山西五台县代银掌矿区周边及深部找矿问题,在矿区选取6号、8号和12号3条勘探线剖面开展了地电化学方法试验研究,对通电(偶极地电提取)和不通电(泡塑吸附提取)条件下的地电化学方法试验进行了对比分析,验证了该方法在代银掌金多金属矿区找矿中的可行性以及外加电场对勘探效果的影响。研究结果表明:地电化学提取异常在已知金矿体上方显示清晰,与金矿体的赋存位置对应良好,勘探效果显著,说明在山西五台地区运用地电化学方法寻找隐伏金矿床是有效可行的。外加电场确实提高了地电化学提取效率,探测深度也大于不通电下的吸附提取,更加灵敏,对隐伏矿体和弱矿化异常都能有明显显示,异常与深部矿体的赋存位置对应度较高,提取到的矿体信息更加全面完整,对进一步分析地下矿体位置和展布形态有很好的效果,在深部找矿预测中可起到较好的指示效应。

Abstract

In order to solve the problem of prospecting around and deep prospecting in Daiyinzhang mining area in Wutai County,Shanxi Province,the geoelectrochemical exploration method was carried out in the sections of three profiles 6,8 and 12 lines in the mining area,and the geoelectrochemical exploration method test under the conditions of energization (dipolar geoelectric extraction) and non-energization (foam-plastic adsorption extraction) was compared and analyzed in order to verify the feasibility of the method in the area and the influence of the applied electric field on the exploration effect.The results show that the geoele-ctrochemical extraction anomaly is clearly displayed above the known gold orebody,which corresponds well to the occurrence location of the gold orebody,and the exploration effect is remarkable,and it is effective and feasible to use geoelectrochemical methods to find hidden gold deposits in Wutai area of Shanxi Province.The applied electric field does improve the efficiency of geoelectrochemical extraction,the detection depth is also greater than the adsorption extraction without electricity,which is more sensitive,and it can clearly show the hidden orebody and weak mineralization abnormality.The anomaly corresponds to the burial location of the deep orebody,and the extracted orebody information is more comprehensive and complete,which has a good effect on further analysis of the location and distribution form of the underground orebody,and it can play a good indicator effect in deep prospecting prediction.
